How to get list of all cached items by key in Laravel 5?

Question

The Cache class in laravel has methods such as get('itemKey') to retrieve items from the cache, and remember('itemKey', ['myData1', 'myData2']) to save items in the cache.

There is also a method to check if an item exists in the cache: Cache::has('myKey');

Is there any way, (when using the file-based cache driver), to get a list of all items in the cache?

For instance, something that might be named something like "Cache::all()" that would return:

[
    'itemKey' => [
        'myData1',
        'myData2'
   ],
   'myKey' => 'foo'
]

The only way I can think of doing this is to loop through all possible key names using the Cache::has() method. i.e. aaa, aab, aac, aad... but of course, this is not a solution.

I can't see anything in the documentation or the API that describes a function like this, but I don't think its unreasonable to believe that one must exist.

Older answers didn't work for me in Laravel 5.2 so I used this solution:

    $storage = \Cache::getStore(); // will return instance of FileStore
    $filesystem = $storage->getFilesystem(); // will return instance of Filesystem
    $dir = (\Cache::getDirectory());
    $keys = [];
    foreach ($filesystem->allFiles($dir) as $file1) {

        if (is_dir($file1->getPath())) {

            foreach ($filesystem->allFiles($file1->getPath()) as $file2) {
                $keys = array_merge($keys, [$file2->getRealpath() => unserialize(substr(\File::get($file2->getRealpath()), 10))]);
            }
        }
        else {

        }
    }
